Restore Control Feel on Your 4VF with Genuine Futaba Parts

The Futaba Trigger Spring Hook and Swing Arm Set, made for the 4VF transmitter, is a practical replacement to keep your radio feeling factory fresh. It targets worn trigger components to improve consistency and responsiveness when flying or driving.

Why It Helps

Designed to match the original geometry of the 4VF trigger assembly, the spring hook and swing arm return the correct preload and movement. That means reduced play, better feedback through the trigger, and more predictable inputs for precise model control.

Quick Installation Notes

Swap the old parts for the Futaba Trigger Spring Hook and Swing Arm Set with the transmitter powered off. Carefully remove the existing hook and arm, fit the new pieces in place, and check the trigger action before use. A short bench check saves time at the field.

Can I use this kit to tune trigger sensitivity?

This replacement restores original mechanical feel but does not change electronic endpoint or throw. Use transmitter trims and settings for sensitivity adjustments.

Is the fit straightforward for hobbyists?

Yes. The parts are intended as a simple swap for the 4VF. Take your time removing the case and keep track of small screws to ensure a clean reassembly.

Should I lubricate moving parts?

A very light application of a plastic-safe lubricant can help smooth motion, but avoid excess oil which can attract dust and grit.

How often should I inspect these parts?

Inspect trigger components periodically, especially after heavy use or if you notice any change in feel. Early detection prevents sudden failures at the field.
